What is the median of the data set 1, 3, 7, 9, 12?

Explanation:
The median is found by arranging the data in order and taking the middle value. The numbers are already sorted: 1, 3, 7, 9, 12. With five numbers, the middle one is the third entry, which is 7. So the median is 7. The other options don’t fit: 5 and 6 aren’t part of this data set, and 9 isn’t the center in this ordered list.
